Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu
Pull m68nommu updates from Greg Ungerer: "A series of cleanups for the FLAT format binary loader, binfmt_flat, from Christoph. The end goal is to support no-MMU on RISC-V, and the last patch enables that" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu: riscv: add binfmt_flat support binfmt_flat: don't offset the data start binfmt_flat: move the MAX_SHARED_LIBS definition to binfmt_flat.c binfmt_flat: remove the persistent argument from flat_get_addr_from_rp binfmt_flat: provide an asm-generic/flat.h binfmt_flat: make support for old format binaries optional binfmt_flat: add a ARCH_HAS_BINFMT_FLAT option binfmt_flat: add endianess annotations binfmt_flat: use fixed size type for the on-disk format binfmt_flat: consolidate two version of flat_v2_reloc_t binfmt_flat: remove the unused OLD_FLAT_FLAG_RAM definition binfmt_flat: remove the uapi <linux/flat.h> header binfmt_flat: replace flat_argvp_envp_on_stack with a Kconfig variable binfmt_flat: remove flat_old_ram_flag binfmt_flat: provide a default version of flat_get_relocate_addr binfmt_flat: remove flat_set_persistent binfmt_flat: remove flat_reloc_valid
